1.	Yesterday in a conference call with Microsoft people I said the biggest win was for them to support the XML-RPC spec without changes. However, I respect their opinion as much as I respect the opinion of the others who have played a role in the definition of XML-RPC, and if they have needs that we share, it would be bad practice to not support change.
2.	An example of that process was the introduction of the <base64> tag, as proposed by Fredrik Lundh, who has been instrumental in the development and deployment of non-Frontier implementations of XML-RPC. He's an important and respected person in this process. Fredrik posted a message to our discussion group saying that they had added a value type, <base64>, to the Python implementation. My leadership challenged, here's the process I went thru.
3.	Does Lundh have the right to add a new value type to the spec? I side-stepped the question, and instead asked myself if the idea was good. After a little thought I realized that it solved a problem we had encountered, it made text-or-binary representation of information an issue that could be handled at the plumbing level, something we had not been able to achieve in any other way. The idea is great! So I quickly updated the XML-RPC spec to include the new <base64> type.
